You can find screenshots with detailed information about the uniformity on the individual product pages of the tested monitors, which we measure in 15 planes. Below we keep to the ratio of the lowest brightness compared with the highest, for black and white.
Samsung has the best uniformity with the S24D330H. The ASUS BE249QLB and the two Acer monitors are just shy of 80%, which we usually hold as the lower limit for ‘good’. Small differences in brightness are not visible to the naked eye, but more than 20% becomes visible.
The uniformity of black always seems slightly worse in percentages, but do bear in mind that these are only small differences in absolute values. Values higher than 70% are great, below that we are slightly less enthusiastic. The bottom five models slightly disappoint; the Benq GW2470H and the Samsung S24F350FH clearly have a weakness here.
Below you can find a brief explanation of how to interpret the individual uniformity measurements on the individual product pages.
Bear in mind that the colour in the boxes with the uniformity of black, white and the contrast is related to the results of the measurements for that model; not to the absolute values.
- As far as black goes, the lower the measured value, the better (=greener); if the value is higher this means worse (=redder).
- For white the colour coding is different, because there we set a specific brightness of 150 cd/m². That is why values that are closer to this setting green, values that are further away become red – the more they deviate the redder they are.
- As far as contrast is concerned, the highest contrast is green, the lowest is red – the values in between are marked by these colours. Greener is better, redder is worse. We emphasize again that these values are relative: a contrast of 1702:1 is excellent, but if the highest measured contrast is 2581:1, the former value is still marked in red.
- With the colour temperature the measurements are bluer the lower they are, yellower the higher they are.
- Last but not least the colour deviation: here you see a number for the DeltaE value in the boxes, where values below three are barely noticeable with the naked eye. The colour of the boxes shows the colour deviation of gray.
